Figure 17 The PFCTRIPREF Circuit on the EVAL-M3-102T evaluation board

The PFC’s overcurrent protection circuit on the control board EVAL-M3-102T is shown in Figure 15 and Figure

The calculation formula is as follows,

If larger PFC current protection setting value needed, please use smaller resistance of PFC shunt resistor RS1, or

modify the control board EVAL-M3-102T following the previous formula. Please refer to the control board’s user

manual for more details.

Inverter section using CIPOS™ mini IPM

The inverter section is also implemented using the CIPOS™ mini IPM as sketched in Figure 18. The inverter

section of IPM module includes an optimized SOI gate driver and a three-phase inverter consisting of

TRENCHSTOP™ IGBTs and anti parallel diodes.

The three pairs of capacitors C11 and C12, C13 and C14, C15 and C16 are used as bootstrap capacitors to
